MEAII S FOR THE CONSTRUCTION CONCRETE SLABS, WALLS, AN D OTHER STRUCTURES.

Application led July l5, 1919.

(GRNTED UNDER THE PROVSIONS 0F THE ACT OF MARCH 3, 1921, 41 ISTAT. L., 1313.)

grooves and dowels vand of rods passed through loops or eyes formed by the projecting portions of reinforcing rods or bars and the joints enclosed by a filling of concrete said slabs being suitable for the erect-ion oi' structures such. as walls oi' buildings, sea

walls, harbour works, piers of bridges, sunk foundations, rretaining walls, ships, pontoons, tanks, sanitary buildings, hospitals,

barracks, Jfarm buildings, outhouses, cottages and the like.

The chief objects are toprovide slabs or members. constructed of concrete adapted for assemblage and connection in an eiiicacious and expeditious manner and which when erected to form the desired structure shall ensure great strength and stability thereto.

vAccording' s to this invention the. hori- Zontal junctions of the concrete slabs are arranged in staggered relation and strength` ened by grooves and dowels. Additional sei curing devices are provided at the vertical junctions by passing rods or wires transversely through the slabs ormembers and twisting or entwining their ends. y

Slabs or members joined or connected in the manner above described may be arranged to constitute walls and may be arranged in plain or straight formation or they may be Zig-Zag. They may moreover be arranged so as to form cells for the reception of concrete or other heavy material for aflording stability or to constitute watertight compart-A ments in ships or pontoons Stalls in farm buildings or apartments inv cottage and other similar structures. j

In order that the invention may be clearly understood and carried into eifect same will now be more fully described with reference to the accompanying' drawings in which cal oint and combining right-angled walls so asto torni cells chambers or apartments.

Figure 3 is a vview similar to Figure 2 showing a Zig-zag wall and walls to form cells chambers or apartments. j

Figure Ll is a ragmentary view in elevation drawn to a larger scale showng three wall structures and the method of joining or connecting them togethervertically. l

Figures 'and 6 are views also drawn vto a larger scale in transverse section showing respectively a right-angled junction of slabs or members as iii Figures l and 2 and an obtuse angled junction of slabs or members as in Figures 3 and 4. f

rllhe formed concrete slabs l areerected to form al wall yfor Aexample by being placed edgew'ays upon each other the 4horizont-al junctions being effected by means of grooves 2 (Figure 4i) and dowelpins 3. `The arrangement is such that the said junctions of the built-up slabs or members l of onevertical series break oint or are instaggered lrelationship with the junctions 'of ladjoining 'vertical lseries of slabs or members as clearly shown in Figure lthe several junctions being indicated at l. lythe expression stagf ing the horizontal junctions in such a man` ner a very iirm and strong structure is en? sured and the slabs or members being ready prepared the erection is capabley of accom` plishment with great expedition. The slabs or members may be reinforced with the well known expanded metal or wire netting as indicated in broken lines in Figure il. For effecting the vertical junction of the slabs or series of slabs the latter' are provided with steel or other metalrods or `wires 5 embedded thereinP andhaving, projecting portions. looped as at 6 and'tiedor lacedtogether,by.v

metal bars 7 threaded or passed throughV the said loops.. .The contiguous portions, 0f the,

expanded metal"1'eini`orcement Which project from the ends of the-slabs may# also befv engaged by threading the aforesaid bars'7 through" overlapping-'fmeshings or the sai-'d reinforcement and thereby tying or interlocking them1 together. The junctions may be furthersecuredby means of; rods or Wires 8 (see particularly enlarged views Figures 5 and' 6). passed transversely through the material' o'-the slabs or members and having their ends twisted or ent'wined as'at 9; The

interstices. or 4spaces in the joint are filled with Concrete as shown at 10 andthe vertical junction etlfectually secured, the rods, bars and interlacing beingt'hereby concealed and the metal prot'ectedjrom corrosion.

In Figures 1, Q and 5 a iatvvall is shown j having right-angled Walls 11 joined thereto. A methodv or effecting the junction at the angle of these Walls is clearly shown in the large transverse section Figure 5 in Which the Walls y'comprising the slabs 1 are joined withl the Walls. 11 by the yabove described system of interlacing and threading the plain junctions bengindicated at 12 Figure 2l All the metal Work pertaining to the unions isenclosed or concealed by asuitable concrete covering. v

When theWalls are required rto be zig-zag in transverse section as at 1.3 in Figure 3 the apices or angles are joined in a manner 11' upon either side of Walls 1. The method or effecting their union Will however. be

` clearly understood Withouty further descripgard the slab portions 13 -(Figure 3) as rep` tion.

u It will be apparent that the method of' joining concrete slabs such as above described and shown in the drawings Will be found eminently suitable for employment in con-` nection with flooring or rooting same presenting a perfectly Water tight structure capable of use in a flat or zig-zag formi, As-

suming the latter to be desired-one may reresent'ing the roolingand the portions 11. two `or the Walls supporting the same.

By the employment of the herein described readlylprepared slabs or blocks a structure oi' any-V desired-form maybe quickly erected as Owing., to. the avoidance of the delay incidental,l to the time required for large masses or concrete to set or harden the completion of the Worli ot construction is rendered very expeditious. v

The. inventionreadily lends itself to the erection of structures of the cellular type the colis-serving as- Water tight compartments or for the reception of heavy material to increase the stability or the structure or for rooms j or apartments.
